Observations/Retag Guidance:

Use overriding for questions related to hiding members using inheritence.

Use member-hiding for questions related to declaring a class member in a derived class with the same name as a method in a base class, without using the language's explicit "override" mechanism. E.g.: the new modified in c#.

Progress:

The hiding tag is in the process of being burninated. You can help out by reviewing the questions with this tag, and...

editing questions to improve the question and remove the tag (retag-only edits are best left to users with full edit privileges; i.e. > 2k reputation),

flagging/voting to close questions that are duplicates/off-topic/unclear/too broad/opinion-based (users with < 3k reputation can help quite a bit by flagging questions for closure, which helps keep the Close Vote Review Queue full),

voting to delete the questions with this tag (after they have been closed, and only if the entire Q&A contains nothing of value). However, keep in mind that at the end of the burnination process all closed questions containing this tag will be deleted automatically. Thus, there's rarely a need to vote to delete these questions.

Remember that burnination is a clean-up effort!

Salvage whatever possible by editing and re-tagging.

We don't want to destroy value, so salvaging a post should be your first priority. If a question can be saved, please edit it. Your edit should improve all problems with the question and remove the hiding tag, possibly replacing it with another tag, as described above in "Observations/Retag Guidance".

Unsalvageable questions should just be flagged/voted for closure. They don't need to be retagged.

If the question is not appropriate for this site, then don't worry about removing the hiding tag — just flag/vote to close the question.

Do not downvote questions in order to trigger roomba

At the end of the burnination process, all questions which still have the hiding tag should have been closed. These will be mass-deleted, which will remove the tag from the system automatically, with minimal disruption.

Ask for help if you need it.

OK, so there are some questions about the new modifier in c#: When used as a declaration modifier, the new keyword explicitly hides a member that is inherited from a base class. This isn't the same as overriding as the base class member is still present on the derived class, it's just less accessible and replaced with something else. See this answer by Erik Lippert for details. What are we to do with these?

I'm not that sure of the exact tag there, @dbc, but if you feel that there needs to be a new tag created for that, please do feel free to create one, and update this answer asking users to use the tag. Thanks for your help.

Well there's already member-hiding and method-hiding which would seem to apply. In fact the original answer brings these two up along with "property-hiding" (which currently has no questions). this answer gives "member" as the more general term for c# at least, so should we use that (and tag c# method-hiding questions)? method-hiding is more popular for c# though at 43 questions vs 8 questions.

Hmm, member-hiding has guidance Declaring a class member in a derived class with the same name as a method in a base class. so let's go with that.

@dbc, ah, cool. Thanks. Would it make sense to merge the [method-hiding] and [member-hiding] tags, atleast in terms of C#?
– Bhargav Rao♦May 12 '19 at 6:07

Probably. But there are java and a few c++ questions there also and I frame no hypotheses about what to do with them.

That sounds fine to me, thanks. While we're on the same topic of tags, can I get a small help from you on the C# related portion in this other tag merge request? meta.stackoverflow.com/q/381728/4099593. Thanks for your help. (top users in the tag helping out makes it really simple for me, so thanks a lot)
